Thank you for checking out my issue.

Answer 1

Yep! If you --trace the deploy command, the deploy:assets:precompile stage will fail at SSHKit::Runner::ExecuteError: meaning that the prod server can't process your request correctly. Try installing nodejs and yarn on the user you deploy to. Docker simplifies the stack by abstracting much of the production configuration from the developer.

cap production deploy --trace

sudo apt-get install nodejs

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt update

sudo apt install yarn

Answer 2

I got this error because I did not have npm and yarn installed on the server

Answer 3

It seems the server connection was cut abruptly.
Can you check the server if it still has enough disk space?
Also, can you try manually running asset-compile IN the server and see what happens.

RAILS_ENV=production rails assets:precompile

※change to staging or development(depends on your environment).
